🔎 Competitor analysis in guest posting
Where competitor analysis in guest posting starts
Competitor analysis in guest posting is not a one-time check of someone else's articles, but systematic work with their backlink profile, platforms, and topics. The goal is simple: find donors that already bring them traffic and links, and take some of those opportunities for yourself. According to Backlinko, which analyzed 11.8 million Google search results, a page in the first position has on average 3.8 times more backlinks than pages in positions 2-10. This means the gap in search results is almost always visible in the backlink profile, and that is exactly where you need to look for it.
💡 Quick overview: to run competitor analysis in guest posting, follow a clear sequence of steps instead of grabbing the first tool you see.
- Identify 3-5 real competitors by target queries, not by intuition
- Export their backlinks and filter only guest posts
- Find donor overlap using a tool like Link Intersect
- Assess platform quality by real traffic, not just DR
- Build a content gap and prepare pitches for topics your competitor does not have
Below, each step is broken down in detail, with numbers, a table, and a real example from practice.
Why a competitor's backlink profile is the main source of ideas
Most pages on the internet get neither links nor traffic. According to Backlinko, about 95% of all web pages have no backlinks at all, and a 2023 Ahrefs study based on a sample of 14 billion pages showed that 96.55% of them get no traffic from Google at all. Against that backdrop, your competitors that already rank are a rare exception, and their backlink profile is a ready-made map of working platforms.
The logic of competitor analysis in guest posting rests on one idea: if a donor agreed to publish a competitor's article and place a link, they will most likely accept yours too. DemandSage research showed that 64.9% of marketers use guest posting as a link building method, so competition for good platforms is real, and the one who works with data wins.
Backlinks remain one of the key Google ranking factors. This is confirmed in the official documentation in the section on how Google search works, where links are described as a signal of trust in a page. So analyzing a competitor's donors is not spying for curiosity's sake, but a direct path to better rankings.
Step 1: correctly identify your real competitors
A beginner's mistake is treating the industry's big brands as competitors. In guest posting, your competitor is whoever fights for the same queries and the same sites as you. To find them, enter 5-7 of your key topics into search and note the sites that consistently land in the top 10. Those are your direct rivals for links.
Once the list is built, check each one by link profile size and topic. Don't chase giants: if a competitor has tens of thousands of donors, replicating their profile with guest posts is unrealistic. Take those who are 1-2 steps ahead of you, their sites are reachable.
To identify your advantages against rivals, note in advance what makes your content stronger: expertise, case studies, data. This will help at the pitching stage, when a site editor chooses between your article and a competitor's pitch.
Step 2: export and filter your competitor's backlinks
Once competitors are identified, export their backlinks using any link analysis tool. The raw list will be huge, so filter it right away: keep only domains with real editorial content and remove directories, forums, and automated mentions. The guest posts are hiding among what remains.
Telling a guest post from a regular mention is simple. Open the donor page and see whether it has a full author-written piece with a link to the competitor inside the text. If the article is written by an external author and places the link in the body, that's a typical guest post, and the site is open to such pitches.
It's useful to immediately mark which donors send the competitor traffic, not just a link. To do that, study their promotion strategies and match the sites to your article topics.
Which metrics to look at for a donor site
Not all links are equally useful. According to DemandSage, the average paid link costs 83 dollars, while a truly quality one costs 508.95 dollars, so selecting sites directly saves budget. Below is a table with priorities for evaluating a donor.
Metric | What to look at | Why it matters |
|---|---|---|
Organic traffic | Whether there are real visits from search | A site without traffic passes no value |
Topic | Whether the niche matches yours | Topical links are stronger than generic ones |
Author content | Whether it accepts external authors | Confirms guest post potential |
New article frequency | Whether the blog is alive today | Abandoned sites don't get indexed |
Outbound link profile | Whether there's a link spam farm | Spammy donors hurt rather than help |
Step 3: find donor overlap with Link Intersect
The most effective technique in competitor analysis is finding overlaps. Load 2-3 competitors into a tool like Link Intersect and find domains that link to several of them but not to you. If a site has published articles from two of your rivals, the chance it will accept your guest post too is very high.
This method saves dozens of hours. Instead of manually checking hundreds of sites, you get a ready list of donors already tested by competitors in practice. Also study how rivals work on drawing attention to their content, this will hint at which article formats sites publish more readily.
Remember that building links this way requires caution. In 2025 Google stepped up its fight against mass link schemes, and sites selling links in bulk are losing value. Bet on editorial posts with real reader value.
Step 4: evaluate the effectiveness of others' strategies
Competitor analysis in guest posting doesn't end with collecting donors. You need to understand which sites actually work for the competitor. Connect link data with traffic data: if an article on a donor site itself drives visits, that link is worth more than a dozen links from dead sites.
To evaluate the effectiveness of competitors' strategies, use analysis tools for traffic and compare the competitor's ranking dynamics with the moments when new guest posts appeared. This way you will see what actually moved them in the search results and what was a waste of resources.
According to DemandSage, 52.3% of marketers call link building the most difficult part of SEO. That is your window: most competitors work haphazardly, and careful data analysis gives a tangible advantage to whoever follows the process through to the end.
Real case: how a content gap turned into 6 links in a month
A niche investment blog team for retail investors was stuck on the second page of search results. Instead of chaotic outreach, they pulled the backlinks of three direct competitors and ran them through donor intersection analysis. They found 18 sites that had published articles from at least two rivals, but never from them.
Then they built a content gap: topics where competitors ranked and the blog did not. For each topic, they prepared a separate pitch with a unique angle and their own return calculations. Out of 18 sites, nine responded, and six editorial teams published the material within one month.
The result was predictable according to Backlinko's theory: six thematic editorial links from sites with live traffic moved two key blog pages from positions 12-15 into the top 7. The main factor was not volume, but precision: each link came from a donor already validated by competitors. This approach pairs well with how authors build long-term relationships with partners on the marketplace.
Step 5: turn analysis into your own strategy
Data is useless without action. Put everything you found into one document: the donor list, the content gap, site metrics, and priorities by difficulty. That becomes your working guest posting strategy, based not on guesswork but on real competitor behavior.
Prioritize the sites: first, donors from the intersection with high traffic, then topical blogs open to authors, and finally hard targets like brand mentions. According to DemandSage, 67.3% of marketers already use digital PR as a primary channel, so when approaching valuable sites, bring genuinely strong material rather than a templated pitch.
Do not forget to update the analysis regularly. Competitors publish new articles, lose old links, and change sites. A quarterly profile review keeps your strategy current and helps you lock in the benefits of guest blogging for authors.
⁉️🤔 Common questions about competitor analysis in guest posting
How many competitors should you analyze for guest posting?
Three to five direct competitors that rank for your target queries is enough. A larger number blurs focus and drags out the work. The key is to pick those who are one or two steps ahead of you, because their sites are realistically attainable for you to replicate through your own guest articles.
Which tools work for analyzing competitor backlinks?
Any link analysis services with donor export and profile intersection features work, such as Ahrefs or Semrush. Based on industry surveys, Ahrefs is considered one of the most accurate for link data. To start, even free profile checks are enough to gauge the scale of the task.
How does a guest post differ from a regular mention?
A guest post is a full authored article published on someone else's site under your name, with a link inside the editorial text. A regular mention is an incidental link without your involvement in writing the material. For competitor analysis, guest posts matter specifically because those sites are open to new authors.
Can you just copy a competitor's link profile?
You cannot fully copy the profile: some of a competitor's links come from sources that are hard to replicate, such as brand mentions and partnerships. Only a smaller portion of donors is realistically available, and those are the ones to focus on. So you do not copy the entire profile, only the reproducible guest posting sites.
How often should you update competitor analysis?
The optimal cadence is to review competitor link profiles once a quarter. In three months, new donors appear, old links fall off, and publication topics shift. Regular updates keep your strategy from going stale and help you respond to new sites in time, before other authors claim them.
What to do next
Competitor analysis in guest posting only works when it turns into specific pitches to specific sites. Start small: pick three competitors, find ten shared donors, and send your first five proposals this week. Use this platform's tools to analyze and identify your competitive advantage so you can find working sites faster and stay ahead of rivals in guest posting.
